Direct Multipixel Imaging of an exo-Earth with a Solar Gravitational Lens Telescope
According to Einstein’s general theory of relativity, the solar gravity field acts as a lens that may be used focus and greatly amplify light from distant faint sources. Thanks to impressive optical properties of the Solar Gravitational Lens (SGL), in the near future, we could deploy a modest telescope at the focal region of the SGL for direct imaging of a potentially habitable Earth-like exoplanet with a megapixel resolution, not possible with any other astronomical tools. It could also provide high-resolution spectroscopic data to identify a variety of atmospheric biomarkers needed for unambiguous detection of an alien life form.
